{wiki=Karplus_equation}
The Karplus equation is a relationship used in chemistry, particularly in the study of nuclear magnetic resonance (NMR) spectroscopy, to describe the correlation between the coupling constant \\( J \\) of hydrogen atoms and the dihedral angle \\( \\phi \\) between them. It is particularly useful for understanding the coupling observed in aliphatic and aromatic compounds.
